Map showing the location of North Sea study site well 22/10a-4 and other sites described in this study in relation to the main Mesozoic structural elements and distribution of Tertiary sediments and volcanics (modified from several maps from King, 2016).

Downhole distribution of clay minerals for the 22/10a-4 samples as a proportion of the <4 µm fraction, compared to the carbon isotope measurements on total organic carbon (TOC) (from Kender et al., 2012).

Downhole variation in clay mineral indices for the 22/10a-4 samples: K/(I-S) and K-I and %‘sand’ compared to total organic carbon (TOC) isotopic and micropalaeontological proxies from the same core (from Kender et al., 2012). The carbon isotope excursion (CIE) can be correlated to the global CIE of the PETM.
